Ah, but, in kinematic envelope terms the vehicles are relatively short
(16m according to wackyp=E6dia) so the throw on curves would not be as
substantial as an equiv. 20m carriage.

That also depends on the position of the main pin on the bogie and the
corresponding pivot point on the carriage rather than just the vehicle
length. IIRC modern carriages (Mk3 etc.) are in any case tapered to
compensate for their length and thus have a smaller swept path on the
_outside_ of a smallest radius curve than A stock.

I always thought 2.85 (ish) was the absolute maximum width no matter what
the length of the carraiges. Is this not the case?

You don't mind denting them so much on the way out.
